Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To appropriately prevent a bar code from being read two times even in the case of reading the bar code on a sheet an which the plural bar codes are printed. SOLUTION: When demodulation data corresponding to the entire bar code are obtained inside an M10-OK buffer 52, a double read prevention control processing part 45 reports the demodulation data to a read OK processing part 48 on condition that a double read prevention timer 46 is not activated, stores the demodulation data in a multi-stage buffer 54 for single and activates the double read prevention timer 46.

Filed: 1986-09-09
Abstract: PURPOSE:To arbitrarily shift the tuning frequency of a resonance circuit, by connecting a resistor having a prescribed internal capacitance transiently in parallel with a parallel resonance circuit, and tuning it with a prescribed frequency. CONSTITUTION:The resistor 13 is connected in parallel with the parallel resonance circuit 12, and the tuning waveform 14 of a circuit is drawn by an oscilloscope. The value of a reactance L is varied, and the tuning point of the tuning waveform 14 is made coincide with a marker 15 set at a normal tuning frequency fo, and afterwards, the resistor 13 is removed. In such a manner, the tuning waveform 14 is moved to the side of a high frequency as shown in broken line, and the tuning frequency of the parallel resonance circuit 12 is shifted to the side of the high frequency. In other words, since a mico internal capacitance exists in a general resistor, and the capacitance is different according to the kind of the resistor, it is possible to shift the tuning frequency of the circuit by selecting the resistor appropriately.

Abstract: PURPOSE:To make the presence of creep and its intensity selectable by subtracting the desired constant pressure from the detected differential pressure between hydraulic pump/motor ports in preference to control over a shift control device at the specified starting area, and controlling a gear ratio so as not to make this constant pressure exceed a differential pressure limit curve. CONSTITUTION:When differential pressure between both ports of hydraulic pump/motor 7, 8 detected by a differential pressure sensor 57 is held at less than normal relief pressure, a gear ratio is controlled in stepless by a shift control device 51 so as to cause actual speed of an engine 20 to converge on the target speed conformed to opening of a throttle 20a. On the other hand, displacement of the hydraulic pump and the motor 7 and 8 is controlled by an auxiliary gear ratio control device 51 so as not to cause such one that is subtracted the desired constant pressure by a setting knob 61 from differential pressure between both ports of the hydraulic pump and the motor 7 and 8 to exceed a differential pressure limit curve. Thus, the presence of creep and its intensity are selectably by a driver's intention.
